What is the rating of a circuit breaker needed for 300 kv load in 33KV supply line of 33/415 transformer ? Whether 800/1200 amp vaccum circuit breaker can perform for a 33 KV line in input in 415 volt in output of the transformer ?
I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
Why does the speed regulating system adopting I controller have no steady-state error? In this single closed-loop speed regulating system, when the input of the I controller Un=0, what is the output voltage of the regulator? What factors do the output voltage depend on?

plz send me the syllabus or any sample paper for engineer trainee recruitment if any,on ravinder911@yahoo.com
The power factor of the fixed load is 0.8, now the p.f is varying from 0.8 to 0.5.
y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
